Part of playing guitar is that you are generally your own writer and arranger--Blues proves the rule--there are many different positions that you can use, each offering a different range of possibilities, and even when you use the same position as another player, a change in the rhythm pattern a slide, a quirky extension, or even a damped beat, can change the whole nature of what you are playing--

Oddly enough, the old time players used many more different musical ideas and devices than the newer players--it has been pointed out that there is a whole generation of electric players out there whose playing is based on two BB King licks, whose playing was based on 4 T-Bone Walker licks, whose playing was based on 16 Blind Lemon licks, who, on occasion. used 16 licks in a single tune--
